Multi-Axial Duct Expansion & Sizing FAQ
How is the developed fabric belt width (W_dev) calculated for multi-axial movements? +
W_dev = √((L_inst + ΔXe)² + ΔY²) · 1.12 + 2 · W_flange, where L_inst is the installed breech gap, ΔXe is axial extension, ΔY is lateral shear, 1.12 is the 12% FSA-DSJ bulging slack safety factor, and W_flange accounts for both clamping flange faces.
What is the structural reaction force advantage of fabric joints over metallic bellows? +
Metallic bellows generate massive spring forces and pressure thrust (often exceeding 24,000 N), requiring heavy structural steel support. In contrast, fabric expansion joints produce less than 150 N of reaction force, slashing anchor structural loads by over 99%.
How does the dynamic B2B RFQ Data Sheet work? +
Clicking the B2B RFQ button instantaneously compiles all entered duct geometry, multi-axial kinematic movements, operating temperatures, and calculated sizing dimensions into a print-ready engineering data sheet with BundleTec quality certifications.
